Supply and extraction ventilators

The ventilators need to be tested according to EN 12101-3. They must also have a certificate handed out by an independent testing organisation (determined in the EN). These must be type F 200 (200°C resistant for one hour) or F300 (300°C resistant for one hour), depending on the site. A lot of attention should be paid to the head of the discharge of the ventilator as well as the back-up that is compulsory in the Belgian norm.

Impulse ventilators

The main advantage of impulse ventilators is that they can be equipped with silencers so they are silent in the event of daily use and have continuous horizontal air displacement. The ventilators have to best tested according to EN 12101-3. They must have a certificate handed out by the testing organisation (determined in the EN). This must be F300 (300°C resistant for one hour). The power-circuit breakers must have the same temperature resistance.

Induction ventilators

The main advantage of induction ventilators is that they are not very high so they do not form an extra obstacle in car parks with limited height. The disadvantage of this type is the lack of silencers and suction underneath. The ventilators have to be tested according to EN 12101-3. They must have a certificate handed out by the testing organisation (determined in the EN). This must be F300 (300°C resistant for one hour). The power-circuit breakers must have the same temperature resistance.
